5128A RHapid-Cal® Humidity Calibrator Introduction

The 5128A RHapid-Cal® Humidity Generator is a portable humidity generator for calibrating a large workload of probes in the laboratory or on-site in the field. It is used by corporate and independent calibration labs where humidity measurement is critical to prevent spoilage of products in industries including pharmaceuticals, medical devices, semiconductors, chemicals, and food production.

There are seven key features that distinguish the 5128A RHapid-Cal®.
  1. Excellent stability and uniformity for accurate, dependable humidity probe calibration
  2. Rapid humidity and temperature stabilization time for high calibration throughput
  3. Supports on-site, multi-point calibration of humidity probes
  4. Versatile design accommodates a large workload
  5. Compact size and lightweight for easy transport
  6. ISO 17025 accredited system calibration included standard
  7. Easy to maintain
First, “excellent stability and uniformity."  Chamber stability and uniformity are two important specifications that impact accurate, dependable humidity probe calibration.  The 5128A RHapid-Cal® offers excellent stability and uniformity for a portable humidity generator.  Some competing generators don't even specify any measure of uniformity.
 
The 5128A RHapid-Cal® incorporates an internal probe for easy sensor calibration and to save the expense of an external reference.  But an external reference, such as a chilled mirror hygrometer, can also be used to obtain lower calibration uncertainties.
 
Second, “rapid humidity and temperature stabilization time" for high calibration throughput.  The materials and air flow design used in the 5128A RHapid-Cal® are selected to ensure that response time to a humidity temperature step change is fast.
 
A six-point calibration can be done in two hours using the 5128A RHapid-Cal®.  In contrast, a two-pressure humidity generator takes longer to respond to humidity or temperature changes.  A similar six-point calibration with a typical two-pressure generator would take more than three hours. 
 
Third, "support for on-site, multi-point calibration of humidity probes."  Spot-check or one-point probe calibration using a handheld humidity meter in the field is convenient, but limited in value.
 
When calibrating with a handheld meter, external influences can cause humidity measurement errors.  And one-point tests may cause out of tolerance readings when ambient conditions change.
 
Using the 5128A RHapid-Cal® to calibrate over multiple humidity and temperature points gives a more reliable test and truer characterization of how a humidity probe actually operates over its working range in the field.  
 
Fourth, "versatile design accommodates a large workload."  A large variety of humidity sensors can be accommodated in the 5128A test chamber.  The 5128A comes with a five-port door for calibrating up to five humidity probes, meters, and transmitters at a time.
 
An optional transparent door with a shelf is available.  Data loggers are placed on the shelf inside the chamber for calibration.  The mixing insert can be removed to accommodate larger devices in the chamber.

Fifth, compact size and lightweight for easy transport.  It can be easily carried to any desired bench space in the lab or transported on-site to a field work location.  
 
In comparison, a two-pressure humidity generator is practically limited to laboratory use because of its large size.  It includes a generator, compressor, and supporting equipment.  A “small” two-pressure generator requires about eight times the space that the 5128A RHapid-Cal® does and weighs about four times as much.
 
The 5128A is lighter than most transportable humidity generators in its class.  It is easily placed on a small cart for plant-wide transport.  A convenient wheeled transport case is offered for shipment or transport to on-site calibrations.

Sixth, Fluke accredited system calibration included.  Prior to shipment, each 5128A RHapid-Cal® receives an ISO 17025 accredited system calibration by Fluke.  The humidity chamber with its internal reference probe is calibrated using a chilled mirror hygrometer as the reference standard.  This system calibration provides the assurance that the 5128A and its internal reference probe have been optimized for the best performance when they leave the factory.  

Seventh, easy to maintain.  The 5128A RHapid-Cal® uses a mixed-flow method to generate relative humidity.  A desiccant cartridge provides a source of low humidity and an internal humidifier generates high humidity.  A display light indicates when the desiccant cartridge needs to be replaced.
 
The 5128A front-loading internal desiccant cartridge design adds convenience and ruggedness.  The desiccant cartridge can be easily changed by removing the front cap and sliding in a new one.

Only clean distilled water is needed to operate the 5128A RHapid-Cal®.  Compressed air or other additional fluids are not required.  A water level indicator on the front panel shows status of water level in the humidity generator.  When the water level falls below “Min”, use clean distilled water to fill the reservoir.
